Description
Porro Prisms by Rocky Mountain Instrument Co. are designed to leverage the principle of total internal reflection (TIR), ensuring that light entering perpendicularly through the entrance and exit surfaces is efficiently reflected by the two roof surfaces. This unique design allows the light to emerge parallel to its original path, making Porro Prisms an essential component in optical systems requiring precise light manipulation.
In scenarios where the acceptance angle for TIR is surpassed or where maintaining clean reflecting surfaces is challenging, Porro Prisms offer the flexibility of applying a metal or dielectric coating to enhance performance. This adaptability makes them suitable for a wide range of optical applications, ensuring reliability and precision even in demanding environments.
At Rocky Mountain Instrument Co., we pride ourselves on a collaborative approach with our clients, engaging in the early stages of development to transition prototype concepts into efficient, manufacturable solutions. Our commitment to quality and innovation ensures that our Porro Prisms meet the highest industry standards, providing exceptional performance in diverse optical systems.
